The effort to develop CALL can be thought of as progressing through three eras. In the first era, the technology itself led the way; constraints on hardware and software dictated the pedagogical uses to which we could put the machinery. In the second era - where we still find ourselves - language teaching leads the way. In the third era - the golden age of CALL - it will be language learning which motivates and controls the development of the whole effort, but we are not there yet. (I shall discuss in more detail why I believe that current developments in ‘learner-centred’ and ‘learner-controlled’ activities on the computer do not as yet really qualify as computer-assisted language learning.)
